Antibacterial plastics

Abstract

The invention relates to the technical field of plastic materials and particularly relates to antibacterial plastics. The antibacterial plastics are prepared from the following substances in parts by weight: 80-100 parts of resin, 35-45 parts of triphenyl phosphate, 25-35 parts of calcium carbonate, 25-35 parts of phenyl salicylate, 15-25 parts of copper-loaded zirconium phosphate, 8-12 parts of dicyanodiamide, 3-5 parts of tribasic lead sulfate, 8-12 parts of POE, 5-8 parts of magnesium salt whiskers, 8-15 parts of conjugated system organics, 25-45 parts of jute fibers, 25-35 parts of epoxidized soybean oil, 8-15 parts of ferrocene, 15-35 parts of stearate, 25-45 parts of chitosan grafted methyl methacrylate, 5-8 parts of toughener, 8-12 parts of antibacterial agent and 25-35 parts of nano aluminum hydroxide. According to the antibacterial plastics provided by the invention, a macromolecular bactericide is adopted, the bactericidal capability is higher, the cost is reasonable, substances harmful to human bodies such as heavy-metal ions cannot be released, and the mechanical strength of the plastics is not affected, particularly the thermal deformation temperature, mechanical temperature and electrical insulating performance of plastic products are not lowered.

Description

technical field [0001] The invention relates to the technical field of plastic materials, in particular to an antibacterial plastic. Background technique [0002] With the development and progress of society and the improvement of material living standards, people have higher and higher requirements for living and working environment, especially hygienic environment. Because plastic has the advantages of light weight, no rust, and good insulation, it is used in many links in the production of home appliances. But in daily life, quite a few harmful bacteria exist and multiply on the surface of plastic products, such as: telephones, washing machines, computers, refrigerators, electrical switches, etc., and cause various diseases through contact; People who come into contact with various bacteria, molds and other microorganisms will become the source of bacterial pollution and disease transmission. However, as people's awareness of health and environmental protection continue...

AI Technical Summary

Problems solved by technology

Silver ions have the strongest antibacterial performance, but their chemical properties are active, and they are easily converted into brown silver oxide or black elemental silver, so they are not suitable for large-scale application in white household appliances.

The antibacterial strength of zinc is only 1 / 1000 of that of silver; copper ions are colored, and a large amount of use will affect the appearance of the product

Although metal ions are quick to sterilize, they are expensive to use in large quantities, and the release of heavy metal ions will have adverse effects on the environment and human health.

The latter has high photocatalytic activity, strong antibacterial persistence, low price and non-toxicity, and strong self-cleaning function. Light exposure applications are limited
